To all whom it may concern:

Be it known that I, CHARLES T. BLACK- man, a citizen of the United States, and a resident of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification, reference being had; to the accompanying-drawings.

invention particularly 'relates to printing-presses of the class' wherein the impression cylinder is opposed to a reciprocatory form-bed.

Theprincipal objects of this invention are, to provide a printing-press with means whereby separate impressions are made by the same type, upon one side ofV- each sheet of paper -fed to the press during a complete cycle of printing mechanism; to provide meansto shift said sheet relative to the face of `the impression cylinderY atter being impressedby the type fwhiile the type form is traveling in one directiomto present a blank portion on the same side of said sheet tor a separate impression by said type on the return stroke of said type form; to provide gripping means to alternately hold the opposite ends of said sheets with respect to the direction of travel of said sheets, `subst-antially in contact with the surface of said .impression cylinder; and to provide means whereby the printed sheets may be delivered from the feeding side of said press with their printed side up.

Further objects of this invention are, to

' providel a printing-press of simplified construction, and consequently of economical manufacture, that wizll ha ve a roducing capacity greatly in excess of similar machines of ordinaryV construction. f-

The form of this invention as hereinafter described provides a printing-press with a reciprocatory form-bed having a rack in toothed engagement with a gear on an oscillatory impression cylinder; means to reciprocate said form-bed; a type form car'- ried by said form-bed.; gripping mechanism carried by said cylinder arrangedV to hold the sheet in one direction of movement of said cylinder; means arranged to shift, said gripping mechanism substantially at the termination of each rotative movement otoscllation of said cylinder, to draw the printed porticn'of said shoot from the region en-` gaged by the type, and present a blank .portion at saidregion to be impressed on the reverse rotative movement of oscillation of said cylinder; a duct in said cylinder, opening through a transverseseries of perforations in the cylindricalwall ofl said cylinder; means to produce a partial vacuum in said duct. and perforations, whereby the atmosphere impinges upon said sheet and A retains it 'm contactl with said cylinder inde,- pendently of said gripping mechanism at the opposite edge, duriiigthe reverse rotative movement of oscillation; means to control the gripping mechanism,l and the vacuum producing. means, whereby the sheet to be printed is engaged at its Vforward' end, with respcct'to the direction in which said sheet is to. be carried'.

This invention further inclgudes the various novel: features of construction and arrangement which are hereinafter more defi- .nitely specified. i

In the accompanying drawings, Figure 1 is a side elevation of a printing-press, showingthe preferred embodiment yof this invention; Fig. 2 is a plan view of the printing-press shown in 1; Fig. 3, is an enlarged diagrammatic e vational view of the movable parts exclusive ofthe frame, showingA said parts in the initial position indicated inY Fig. L', Fig. 4 is a diagrammatic elevational view similar to Fig. 3, showing the parts shifted to a position wherein the cylinder. and form-bed have nearly completed the first half of their cycle oi? movement, and: showing the shifted relative to the surface of the cylinder; Fig. 5. is a diagrammatic elevational view. similar. to Figs. 3 4i, showing: the parts shifted-to the posit-ion opposite to. that shown in Fig. 3;v Fig. 6 is an enlarged longitudinal sectional view of the impression cylinder, taken in two planes intersecting on the axial line of said cylinder, as indicated by the lines 6-6 in Fig. 3; Fig. 7 is a staggered transverse sectional view taken in two parallel planes, as indicated` by the lines 7 7 in Fig. 6;V Fig. 8 is a face view of the pump actuating cam; Eig. 9 is an enlarged transverse sectional view similar to F 'r 7 taken gn the lines 7-7 in Fig. 6 and loo ing at thoside opposite to that shown in Fi 7.z and 'sh-ewig in detail theV ffmake-r y mechanismT Fig. 10` is a side elevational .view 01'! aprinting-press similar to. that *shown in 1;, embodying a slightly modied form of impression cylinder; Figs. 1l to 15inlusive, diagrammatically illustrate dili'erent positions of a modilication of this invention, wherein the printed sheet is teinporarily discharged from the cylinder after its first impression, .1nd automatically picked up again and married in diferent relation to the cylinder surface; and Figs. 16 to 20,l

inclusive, diagrammatically illustrate a modiiication of tl. is invention wherein means is provided to temporarily retain the gripper arms in predetermined pos1t1ons, and the rotation of the cylinder elfects the relative shifting of tlie cylinder' surface and the sheet to be printed.

In said figures, the frame comprises the side standards 12 and 13, which provide bearings for the main shaft 14 and drivingI sha ft 15, which lat-ter carries the usual tight and loose pulleys 16 and 17 and the il wheel 18, and is provided with the gear 19 in mesh with the gear 2O on said main shaft 14 The main shaft 14' comprises the crank arms 2l, having the crank pin 22, which carries the roller arranged to play in the slot 21, in the depcndir. g yoke Q5, which is secured to, and carried by the reciprocatory fornrbed 26, whereby the rotation of said crank arms 21 impart-s a Vvariable rectilinea motion to said forni-bed 26.

Theiorm-bed 26 is provided with the rack 12S, which is in toothed engagement with the gear 29 on the impression cylinder 30, So that as the fornrlied is rtciprocated by the engagement ot' the roller 23 with the yolte 25, the impression cylinder 30 is oscillated thereby at the same surface speed. The imon cylinder 30 is jourr aled in the bear- 2 on a stationary' axis, its surface being at all times in position to impress upon the type 33 of the type form 34, carried by Said forni-lied 26. 'lhe form-bed mounted to rcciiirocate in the guides 31" and Pio in the ,respective side standards and 13, and is provided with the usual ink distributing plate l0, which is arranged to engage the ink distributing rollers 41 and 4Q at each reciprocation of said form-bed, said ink distrihuting rollers being journaled in suitable lwarings carried hy said side standards 13 and lll.

The side standards 12 and 13 are provided with upwardly extending supports 44, which carry the feeding mechanism comprising the incli'ed table 45, from which the sheets of paper (lo are fed to the gripping mechav nism, comprising the gripping lingers 4S' carried by the gripper arms 49, whirl; are li'iosely mounted on the. shaft 50 of' the cylin der il() and prevented from accidental displm-ornent in an axial direction by the col lars 552. which are secured in fixed position on said shaft by the set screws 53. The gripper arms 4) extend through slots 5l in the cylindrical wall of the cylinder 30,

and are connected by a rod 56 which extends through said gripper arms il), and projects through slots 57 and 58 in the end walls 59 and 60 respectively, in engagement with the ends of the gripper levers 61 und 62.

The gripper lever 61 comprises the gear 63, `which is in mesh with the gear 6l on the shaft 65 extending through the impression cylinder 30 and journaled in its respective end Walls 59 and 60. Said shaft 65 has the gear 66 in mesh with the gear 67 on the lever 62, which is rotatively mounted on the hub 68 of the impression cylinder' ld The gear 63 is rotatively mounted on the huh 6l) of said impression cylinder El() and is pro `vided. with Aa sleeve i0. Said sleeve. 7() extends through the hearings 3Q and is provided cxterior to said bearinr with the gear 72, which is normally ont et mhh with thc sector gear 75, but which, however, is ar ranged to he rotated hy id sector gear, when the latter is shifted in the direction of the arrow indicated thereon, from. the post tion shown in 'Figsn i, and 6 to the position indicated in Fig. 5, or when shifted in the reverse direction. The cylinder 3() is conveniently secured to the shaft :30 by the key 74, which is engaged with a lzcyvvey in said hub 69.

The shifting of the sector 75 from the p0-- sition shown in Figs. 1 and 3 to that shown in Fig. 5 eliects the movement of the gripper levers 61 and and consequently the gripper arms it), relative to the impression cylinder 30 in the direction ot' the arrow indicated in Fig. 1, through an are limited by the slots i? and from the rear end of said siots to the forward ond during a portion of the rotative movement o oscillation of the impression cylinder lo cylinder trai filing in the direction of the arrow indicated in lf'ig. l, and from the forward end to the rear end of said slots durinv a portion of the reverse movement of said im A -ssion cylinder. fit is to lie noted that the movement ot id gripolng ai :hanism is not g effected until the c vlin erlitt has nearly cornpleted its rotative movement. of oscillation in either direction, hut eected in time to present the blank portion of the printed sheet over the region of the cylinder which always registers with the type in either direetion.

mospheric fessure impin g u` on the surface of sa d paper, whic is e ected by a partial vacuum produced in thcolined series of perforations 85, in the cylindrical wall of said cylinder. Said series of perforations respectively extend across the cylinder -i'n parallel relation with its axis, at relatively diierent distances from the gripping lingers, and are in communication with the duct 86, which is formed in the cylinder wall 55 and which is connected by the pipe `87Iwith the duet 88 leading through theV shaft't), which latter is' connected through the -stuiiing box' 90 withthe' 91 lending tothe pneumatic cylinder. 92; y aid cylinder 92 is provided with the pistonY 95 having a piston rod 96 provided within -cam roller 97 arranged to travcrse'the earn groove 98 in the cam 100, which is secured on the Thegrwve' of the cam 100jis so designed that the pis-l ton 95 is slowly moved to :form a partial vacuum beginning with the reverse rotative movement of the cylinder 30 in opposition to the' arrow indicated in Fig. 1 and continuingv until the edge of the., oper 46 .reaches the delivery side of- 't e press, whereupon said piston 95 `is suddenly shifted to create pressure therein, and thereby blow the' edge of the paper 46 from `the cylinder sufface, to be deected by the stripper fingers l103 and guided thereby between the cofhveyer belts 104 and 105, which arc carried bythe rollers 106 and 107. The roller 107', at the outer end of said conveyor belt is provided with the small pulley 108, connected by the belt 109 with the relatively la-rge pulley 110 on the mein shaft 14, so that, as may be observed, said conveyor belts are actuated at a comparatively high rate of speed and thereby carry' the printed sheets from the cylinder ont of the path of the rapidly-returning gripping iinlfiers at thevtcrmination of the cycle o'f eperation of the cylinder 30.

The press above described operates as follows: Sheets of paper 4.6 are consecutively `i3d upon the feeding table 45, with the printing mechanism in the initial position shown in Fig. 1, to the gripper fin ers 48, which by the rotative movement o the cylinder 30, in the direction indicated by the arrow, thereon draws each sheet from the feeding impressed u` n on'e portion of one side thereof, by t e type 33, which continues to mately one revo ution, during the latter portion ofwhich the cam 82 eifccts the movement'o'f the sector 75 to shift the gripper mechanism forward to the position paper' 46 to 1 such position 'that its blank region will ybe impressed by the type 33 bed 26 and the corresponding rotative movement of oscillation of the cylinder 30 in a direction opposite to that indicated bythe arrow thereon in Fig. 1. Afterthe cylinder 30 has made its complete revolution in one direction, however, 'the cam 100 effects a continued movement of the piston 95 to produce a partiel vacuum in the duct 86, which causes the atmospheric air to impinge upon the edge of the paper 46 which is opposite to the edge first gri pcd by the gripping mechanism, and -sei move in' such direction asto maintain said partial `vecur'nn during' the-reverse rotative movement of oscillation4 of the cylinder, until said `cylinderis" in a'positionto discharge sud only shifted in the opposite direction to produce pressure within said duct Sii-to blow the edge ofthe sheet of paper 46 sway from the cylinder, and into positionv tobe guided by-fthe stripper lingers 103, between the,opposed conveyer belts 104; and 10.5, which' arel rotated atsuch speed as to uiclrl withdrew scid printed sheet from t 1e cy ider in order to' clear the way for the movement of the gripper arms, which is eifected by the reverse movement of the sector 7 5 approximately at the letter portion of the reverse rotative movement of oscillation of the cylinder 30 to its initial gposition, as shown in Fig. 1, ready to receive the bl'anlrsheet of paper.

The impression cylinder may be provided which, s illustrated in Fig. 9, com rises a blanket 105, preferably formed 0F heavy paper which may be secured, at cud the clamping device 107, cariedlfbythe cylinder 30, and which is wrapped around the de sed surface 10S of the cylinder 3o an .attachsd at che other sndto che takeup roller 109, which is journaled in which is retained in adjusted position by r theratebet 110and its pawl 111.

shown in Fig. 5, which shifts said sheet of piston continues to 125 mutable bearings in the cylinder 30 andferred to provide apertures 112 in registry with the desired series of peforationsl 85 in the impression cylinder 30; for instance, if a sheet/to be printed is of maximum length, the apertures 112 in the blanket 106 will be made to register with the perforar` tions which are most remote from the gripping fingers 48, and the different series of lperiorations 85 may be utilized in connection with the printing of sheets of different lengths.

The form of this invention shown in Fig. 10 is particularly adapted to be used with. automatic icedin mechanism, of which there are many We l known forms. The ink pression cylinder 115 carries the gear 116, which is in toothed engagement with the rack 28, and which is so proportioned that during each stroke of rcciprocation of the form-bed 2G, the cylinder 11:3 makes approximately one and one-half revolutions for each rotative movement oi oscillation.

AA separate sheet of paper 118 is fed from the feeding table 119 at the beginning of each rotative movement of oscillation, the alternate sheets being gripped by the gripping ngers 120 at the beginning of the for- Ward-rotative movement. Said iingers 120 are arranged to oscillate on a. fixed pifvot 121 to grasp said paper 118, which is carried by said fingers and presented in position to be impressed by the type 33 during said forward rotative movement of oscillation of said cylinder, the discharge of said paper being conveniently effected by the stripper fingers 124, which direct the sheets 118 between the conveyor belts 125 and 126. T he further rotation of the impression cylinder 11S-presents the gripping mechanism in posit-ion to grasp the second sheet of paper 118 during the forward rotative movement of oscillation of said cylinder, and to draw said peper from the feeding table 119, Whereupon the opposite edge of the paper from that edge which is' gripped Iby the gripping mechanism overlies the vacuum duct 12'?, and vacuum is'eective during the reverse rotative movement of oscillation 01"' said cylinder 115 by the actuation oi the vacuum cylinder or pump 128, which is connected by the pipe 129 through the shat't130 and pipe 131', with said vacuum duct-127.

Vacuum is producedy in the cylinder or pump 128 by the movement of the piston A133, having the connecting rod 134 arranged to slide in the guide 135 and provided with the roller 13G arranged to traverse the cam groove 137 in the cam 138 on the shaft 14. Said groove l137 is so designed to produce a partial vacuum during a considerable portion of the reverse rotative movement of oscillation of the cylinder 115, until the sheet 118 held thereby is carried to the discharge position at the side of the press from which it was fed thereto.

When the discharge position is reached, the piston 133 is suddenly shifted b the cam 138 in the opposite direction to e ectpressure in the duct 127 to blow the edge of the sheet 118 from the cylinder into the path of the stripper fingers'140, Which deflect said sheet and direct it between the discharge conveyer belts 1-1-1 and 142, which are driven by the belt 150 connecting the pulley 151 on the shaft 152, with the pulley 153 on the shaft 154. Said shaft 154 is driven by the belt 15G, which connects the pulley 157 with the pulley 158 on the shaft 14.' f

Although certain of the parts, such as, for instance, the pipe 91 and the belt 109, shown in Fig. 2, are extended from the press frame merely for convenience of illustration, in

practice they may be disposed close to or even between the frame standards to permit rce access to the press.

I1`he press illustratedin Fig. 10 is substantially identical with the press'shown in Fig. l, with the exception of the impression cylinder, which, it is to be understood, may be interchangeable, so that the same press frame may be used with the different forms of cylinder, which are interchangeable and which may be substituted one for the other.

1n the form of this invention shown in Figs. 11 to 15 inclusive, the cylinder 160 is provided with the gripping lingers 161 arranged to grasp the sheet 162, and by the rotative movement of oscillation of said.

ycylinder in the direction indicated by the arrow in Fig. 11, draws said sheet from `the feeding vtable. 163 and presents the forward half of said sheet to be'impressed by the type 164, as shown in Fig. 12.

lVhen the forward edge of the sheet 162 reaches a predetermined position, after said sheet is first impressed, it is released by said gripping fingers 161, and directed by the stripping fingers 165 onto the support 166, which is preferably a. conveyor belt traveling in the direction indicated by the arrows in Figs. 11 to 15 inclusive, and which temporarily supports the partly printed sheet, which is cast oid by theA cylinder 160, and

which is limited in its movement on said belt by the stop or gate 167 with its rear edge overlying the face of said cylinder 160, as shown in Fig. 13. 1t may be noted that said belt support may be disposedin different positions as indicatedin dot-ted lines to accommodate sheets of diierent length. The further rotation of the cylinder 16'n presents the vacuum gripping mechanism 168 beneath the end overlying the cylinder, and a partial vacuum is applied to engage said sheet with .said cylinder, which latter reverses its rotation of oscillation as the type travels in thc direction of the arrowindicated in. Figs. 13 and 14 and presents the. blank portion of said sheet in position to be impressed by the type upon its return move- 4`by said ty ment of t e printing mechanism, the pneument of reciprocation. After said sheet has been twice impressed during the cycle of the printing mechanism it is released by the pneumatic gripping mechanism and directed y the stripping fingers 170 between the conveyer belts 171 and 172 and discharged thereby.

In the form ofthis invention shown in Figs. 16 to 20 inclusive, the impression cyliuder 175 is provided with the movable gripper arms 176, loosely journaled on the shaft 177-. Said gripper arms 176 are connected by the rod 178, which carries the gripping lingers- 17 9, which are arranged to grasp the sheet 180. By the rotative movement of oscillation of the cylinder 175 in the direction of the arrow indicated in Fig. 16, said sheet 180 is drawn from the feeding table 181 and presented in position to be impressed by the type 182 traveling in the direction of the arrow indicated in Fig. 16 until said cylinder occupies the position shown in Fig. 17 and the type 182 has shifted to the end of its initial stroke of reciprocation, whereupon the gripper arm 176 is temporarily retained by the frictional engagement with the depression 183 in the gripper arm 176, of thelretaining spring 184, which is carried by the' frame of the press. By the rotative movement of oscillation of the cylinder 175 in; the direction indicated by the arrow in 18, the face of the cylinder 175 is shifted relative to the sheet 180 until the rod 178 is engaged by the end of the slot 185 and the gripper arms 176 are released from the spring 184 by the rotation of said cylinder.

he relative movement of the cylinder and sheet presents said sheet in position on said cylinder 175 to be engaged by the vacuum gripping mechanism 186, which holds said sheet in position on said cylinder to present its blank portion to be impressed by the type 182 in moving in a direction of the arrow indicattdin Fig. 18. After being impressed twice during the cycle of movematic gripping mechanism releases the sheet A`180 in the position to be directed by the v'stripper fingers 189 between the discharge lconveyer belts 190 and 191, which are so rotted as to quickly draw said sheet from said linder to permit the gripper arms 176 and e fingers 179, carried thereby` to return to their initial position to grasp another sheet 180, as shown in Fig. 20, wherein the extreme initial position of the cylinder 17 5 and the type 182 are shown, it being noted that said cylinder must be rotated slightly more than a quarter turn, or enough to effect the engagement of the rod 178 with the rear end of the slot '185 before said gripper arms 176are-rel.ead from the spring catch 192,

which normally tends to hold the gripper alms 176 in their iilitial position.

.:Rfmly belhei md that s press com structed in, accordance with this invention may be operated at a much greater speed than presses heretofore constructed, for the reason that two impressionsiare made -for each feeding operation; therefore, it isV obvious that one operator may produce a considerably greater number of impressions with but one form, and consequently with the preparation of one make-ready. Furthermore, a press constructed in accordance with thisr invention does not require any means for raising the impression cyl-l inderpduring the reverse stroke of the formbed, for the reason that an impression is made during each of the forward and bakward movements of said bed, and owing to the fact that impressions are made on the sheets of paper during both 'the forward an'd backward movements of the press mechanism, said sheets may be discharged from the rintingr mechanism at the end of the mac ine from which they were fed, with the printed side up. f

It is not desired to limit this invention to the precise details of construction andarrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential. features of the invention as defined in the appended claims."
